Hi Pauline,
From my understanding, Perfect UV Protector is more water-resistant – suitable for sports, face and body..
It also contains exclusive skincare benefits and the formulation is so light that it can be removed by using ordinary facial cleansers – yes, no need to use makeup removers..
I feel that the texture is lighter and absorbs faster than Multi-Defense UV Protector..
Bottome line, if you like Multi-Defense UV Protector, you will love Perfect UV Protector!!
Hope it helped =)
